Digitizing high-quality microscopic images and developing input/output technology for displaying those results is critical to telepathology in which pathological microscopic images are transferred to remote locations where they are diagnosed by specialists. This paper will discuss the results achieved by directly digitizing (nonfilm process) pathological(More)
Simple chest X rays on film are the most common type of image in medical diagnosis. However, amongst the various types of medical X-ray images, they require the highest level of display quality due to the fact that the body structures they capture on film have varying degrees of permeability to X rays. Conventional high-definition digital display technology(More)
Vanadium dioxide (VO 2) is a promising reconfigurable optical material and has long been a focus of condensed matter research owing to its distinctive semiconductor-to-metal phase transition (SMT), a feature that has stimulated recent development of thermally reconfigurable photonic, plasmonic, and metamaterial structures. Here, we integrate VO 2 onto(More)
We investigate the hole dynamics in two prototypical high temperature superconducting systems: La 2−x Sr x CuO 4 and YBa 2 Cu 3 O y , using a combination of dc transport and infrared spectroscopy. By exploring the effective spectral weight obtained with optics in conjunction with dc Hall results, we find that the transition to the Mott insulating state in(More)
